自己写得串口多线程控制程序，里面的超时设置和书上说得不是很一样，大家参考吧...

详细介绍了在Windows环境下应用VC与PC机和单片机进行串行通信的几种方法，我们用visualc6.0编写了PC机与C51单片机的通信程序。经实际应用系统运行稳定可靠。

本文介绍的用 89C51 单片机I/O 口模拟实现串行通信的方法，已成功 地应用在某电压数据采集系统中，实践证明能可靠地传送和接收数据。-This article describes using 89C51 microcontroller I/O port Serial communication simulation method has been successfully applied in a certain voltage data acquisition system, the practice has proven to be a reliable way to send and receive data.

提供I2C总线初始化、工作时的启始位、结束位、提供I2C总线的时钟信号，并返回在时钟电平为高期间 SDA信号线上状态。本函数可用于数据发送，也可用于数据接收-provide I2C bus initialization, the Start-end, provide the I2C bus clock signal, the clock and return to the high-level signal line during the SDA state. This function can be used to transmit data, can also be used for data reception

本人所编的一个关于RS232传输的小程序，可以传送数据，请大家多指教啊-I have made a transmission on the RS232 applet, you can transmit data, please advise U.S. multi-ah

串口编程的是反例子，可用于测试你的串口通行-anti-examples can be used to test your serial port access

用C51编写的基于51单片机串口点对点双向通信程序，特点是具有可靠的通信失败检测及信息重发功能。-with C51 prepared by the 51 microcontroller-based point-to-point two-way serial communication program, which is characterized with reliable communication failure detection and re-issued the information function.

串口通讯开发文档资料，四个word文档，详细描述如何串口开发-VC_COMM content

一个串口通信的例子，选取接口，然后可以接受和发送数据。-A serial communication example, select the interface, and then can receive and send data.
